Coaxial-shearing type banana straw crushing and returning machine

Abstract

The invention, which belongs to the technical field o the agricultural machinery, relates to a coaxial-shearing type banana straw crushing and returning machine. A hitching device, a driving device, a coaxial shearing device and a tackling device are successively arranged on a rack from top to bottom. Travelling devices are arranged at two sides of the rack. The coaxial-shearing type banana straw crushing and returning machine is connected with a tractor by the hitching device arranged at the front end of the upper side of the rack; the power of the tractor is transmitted to an inner rotating shaft and an outer rotating cylinder of the coaxial-shearing device by the driving device, thereby realizing reverse rotation of the inner rotating shaft and the outer rotating cylinder of the coaxial-shearing device and thus driving an inner shaft rotating knife body of the inner rotating shaft and an outer cylinder rotating knife body of the outer rotating cylinder to cut and crush banana straws. According to the invention, the coaxial-shearing device in reverse rotation is used for crush the banana straws in the banana growth field. The overall structure is simple and compact; a fiber winding phenomenon is reduced during working; the high-efficiency banana straw crushing and returning are realized; pollution caused by straw corrosion in field can be avoided; and the machine is suitable for the banana straw crushing and returning work at the banana producing area.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a coaxial pair-scissor type banana straw crushing and returning machine. Background technique [0002] Banana straw is the main by-product of banana production areas. In 2013, the banana planting area in my country was about 427,000 hectares, and the biomass of banana stems reached 38 million tons. At present, the vast majority of banana pseudostems still use the traditional method: first remove the leaves and tail tips, and then manually cut them down and transport them to the open space in the field to rot naturally or burn them after they dry up. The mode of processing banana pseudostem like this is not only labor-intensive, production efficiency is low, production cost is high, and can cause environmental pollution, resource waste. [0003] At present, the main factor limiting the low rate of banana straw crushing and returning to the field is the ...
